There are many reasons why you might have CDs in need of a cardboard case. You may have made CD backups of your data and want to store them somewhere that isn't the spindle the blank CDs came on; you may have made a mix tape CD for a friend, or a CD of photos for a family member; or you may simply want to reduce the space taken up by your music collection by getting rid of the jewel cases. You can easily print out customised cardboard sleeves at home.
